RSA cryptography in PHP (How To?)

Being security is one of the utmost considerations in current web site/ application development process, I am sure you have spent a lot of time writing codes to handle encryption in your applications.

In this article I am trying to present one of my favorite ways to solve this issue, the RSA encryption/ decryption handling in your PHP development.
